Biography
Francisco Juan Delgado de Leon was second in command on an expedition to Yucatan from Cuba under Pedro de Alvarado. His successes under Alvarado earned him royal permission to participate in the conquest of the Aztec. He received a ship, a complement or rodeleros, crossbowmen, and the goal of plundering the New World for personal and political gain.

In 1565 he moved on an Aztec city in order to find the map to the Fountain of Youth, which was a legendary spring which would give immortal life. He captured Sahin the Falcon, an explorer of the Ottoman Empire, but did not find out where the fountain was. He had to attack the Aztecs, and was defeated by a combined force of natives, an army from Tenochtitlan, and members of the Knights of St. John. He retreated from the area, but the Knight Morgan Black pursued him and the Spanish treasure fleet in order to pay off his debt to pirate Elisabet Ramsey. He assaulted the fleet, sinking all of the ships and slaying Delgado in his camp.
